03_SEQUOIA_U (L/O 0301) Four −wheel drive system- (a) Front drive control NOTICE Always use the brake pedal or the parking brake to hold the vehicle on an upgrade. Do not attempt to hold the vehicle using the accelerator pedal, as this can cause the transmission to overheat. Use the front drive control lever, "4WD" switch and center differential lock switch to select the transfer and center differential modes. The "H" and "L4" position of the front drive control lever provide either lock or unlock the mode of the center differential. Use the center differential lock system if your wheels get stuck in a ditch, or when you are driving on a slippery or bumpy surface. When the center differential is locked, the vehicle skid control system is automatically turned off and the center differential lock and "VSC OFF" indicator lights come on because the function that controls engine performance interferes with the process of freeing your wheels. "H" (2WD) MODE "H" (4WD) MODE (center differential unlock) or "L4" MODE (center differential unlock) "H" (4WD) MODE (center differential lock) or "L4" MODE (center differential lock) NOTICE As soon as the center differential lock switch is turned on, the "VSC OFF" indicator light comes on. After the wheels are out of the ditch or off the slippery or bumpy surface, turn the center differential lock switch off. Make sure that the center differential lock indicator light and "VSC OFF" indicator light turn off. 147 2003 SEQUOIA from Jan. '03 Prod. (OM34422U)
